Printing apparatus

ABSTRACT

A method and apparatus for printing a plurality of single warp ends of yarn wherein the ends of yarn are passed through a series of printing assemblies, each assembly including a pair of rolllike assemblies at least one of which roll-like assemblies carries a plurality of reciprocally movable pads thereon which can be selectively, reciprocally moved in a pre-determined manner in a direction normal to the longitudinal axis of the roll-like assembly to contact the yarn being printed on. Control of the pads is, in turn, made possible by a plurality of patterned program bars which can be selectively moved in a pre-determined manner in a direction normal to the reciprocal direction of movement of the pads.
